To all ywhom it may romero: I

Be it known that I, HEEMANN LEM?, a citizen of the United/Sto( es, residing at. Lynn, in the oouutyof Essex,

liquids, and especially kerosene oil. lts object is toprovides bur-ner of the injector type, which can be Controlled either by hand or autonnrticully to very the intensity of the re as cirfnrustances may require.

The invention has especial relerenoe tostezuu cnrriages, but is evidently applicable to a Variety of uses.-

In some burners oi this type it has been found necessary to use a. variable opening for the mixed gosesfeqnjointly with o. variable opening in the vapor-nozzle. If the oil pressure is increased without changing the area. of the nir'opening, the excess of vapor will produce n -yellonT flame. lf, on the other hand, the air opening is too large for the pressure at which the Vapor issues from low and the llame will 'shootbeck'zmd burn on the inside. It has thereforebeen necessary either to regulate hothv the air and vapor openings carefully and simultanousl Y, or to keep the burner'lull on while running andfthen shut it off completely While the pilot burner onlgis left lighted.

In' the present invention, the regula-tion is' aecomplished by'proyiding o. plurality. ofh'inixingsf ubos und. :t plurality of' vapor openings, one for er1-oh tube. und n valve which will quickly and completely shut off any number of seid openingsa-twill, thus cutting in or out fof service as many mixing-tubes ne. may be needed. The vapor pressureis maintained constant, so tha-L the relative quantities of vapor and nir supplied to euoh tube nre always the sonic, und ille. flume from euch tubo' iully turned on'. there boing no"inierxmdiulostages This is readily nr'ooxnplished hy providing tho ini-ive- .fontrlliug lover with somo suit-able dovirollor stoliwing it in positions corresponding with they full the seyernl tubos. v u

W-"hat I claim as new and desire to secure by Letters Patentof-tlie United States, is-

1. A hydro-ehrlich burner comprising a nozzle having a plurality` of vapor-dischargingopenings, a radially extend.

Il xgnlixing tube opposite euch opening having a closed .guter end and an open. inner end to receives stream o1 Lqnpor 'groin the opening and also air induced by the sti'e'am, longitudinally movable tubular valve arranged within ejnozzle at a point intermediate the inlet end thereof and the discharging openings and so shaped as to open or close successively a portionofA said openings only, moans for actuating the valve, and a vapprizer for the liquid fuel 'comprising a tulle that' lirst rises vertically and then extends over the mixing tubes and is heated by the flume therefroni.

2'. A hydro-carbon hui-ner comprisingr a nozzle having u plurality of vapor-dlschai-giug openings, a radially extendlug mixing tuile opposite each opening which receives :i stream of vapor therefromnnd also air induced by .the stream, :i longitudinally movable tubular valve within the nozzle so s'ped as to he capable of successively opening or closing all the'dilseliargmg openings-except two which supply vapor to Atheir respective mixing tubes continuously, und :l vziporizer ,common to all of the mixing tubes .nud comprising u tube that first rises vertically and then ex renrls-gicrl-iss tlievburner from side to side und is arranged to eouvey liquid fuel through the llames of the mixing tubes which are in continuous operation to"vaporize the fuel und deliver it to the nozzle. g l

3. A hydro-ciirbon burner eompi'lsing anlv upright nozzle having n lplurality of vener-discharging openings, mixing tubes radiating from the nozzle which receive vapor from. the openings and air induced`v thereby, one or more of the tubes receiving vapor continuously, a tubular, valve longitudinally movable in the nozzle which is adapted to successively open or close the'vapondlsclirgingopenings except the one supplying thelcontinuously operating mixing tube, a vapori'zer. for' liquid fuel having one portion extend- I ing upwardly al: one side ol. the nozzle and tubes and over the same from one side to the other at a slight inclination and another portion extending downwnrdlygand connecting with the nozzle, und a starting Burneruirranged to receive fuel from the nozzle and to heatitlieownwardly extending portion of the vaporizer. 1 I
